We look at the division of 68688631 by 161 
We want to divide 68688631 by 161.

Advancing to step 1:
If we divide 6 by 161, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 161

Advancing to step 2:
161 can be fit into 68 0 times, resulting in a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Fetch the next digit (6) from the dividend, attach it to 68 and continue: 686 / 161

Moving on to step 3:
When dividing 686 by 161, we get 4 with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 644 from 686 and we're left with 42.
Grab the next digit (8) from the dividend, add it to 42, then carry on: 428 / 161

On to step 4:
161 goes into 428 2 times with a remainder of 106.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
The remainder is 106 after subtracting 322 from 428.
Take the next digit (8) from the dividend and append it to 106, then repeat: 1068 / 161

Moving on to step 5:
161 can be fit into 1068 6 times, resulting in a remainder of 102.
The next digit of our result is 6. 
Result so far: 426.0
Subtract 966 from 1068 to get 102.
Include the next digit (6) from the dividend after 102, then repeat: 1026 / 161

Step 6:
When dividing 1026 by 161, we get 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 4266.0
If we subtract 966 from 1026, we get 60.
Grab the next digit (3) from the dividend, add it to 60, then carry on: 603 / 161

Let's proceed to step 7:
The number 161 fits into 603 3 times, leaving a remainder of 120.
Put 3 as the next digit of the answer. 
Result so far: 42663.0
Subtracting 483 from 603 leaves us with 120.
Bring next digit (1) of the dividend behind the 120 and repeat the process: 1201 / 161

Let's proceed to step 8:
161 goes into 1201 7 times with a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 426637.0
If we subtract 1127 from 1201, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 9:
740 divided by 161 is 4 with a remainder of 96.
The next digit of our result is 4. 
Result so far: 426637.4
If we subtract 644 from 740, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 10:
The number 161 fits into 960 5 times, leaving a remainder of 155.
Use 5 as the next digit of our solution. 
Result so far: 426637.45
Subtract 805 from 960 to get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 11:
161 goes into 1550 9 times with a remainder of 101.
The number 9 becomes the next digit in our result. 
Result so far: 426637.459
Subtract 1449 from 1550 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Step 12:
The number 161 fits into 1010 6 times, leaving a remainder of 44.
The next digit of our result is 6. 
Result so far: 426637.4596
Subtract 966 from 1010 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 13:
When dividing 440 by 161, we get 2 with a remainder of 118.
Put 2 as the next digit of the answer. 
Result so far: 426637.45962
Subtract 322 from 440 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 14:
161 can be fit into 1180 7 times, resulting in a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 426637.459627
Deduct 1127 from 1180 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 15:
161 can be fit into 530 3 times, resulting in a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 426637.4596273
Subtract 483 from 530 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 16:
470 divided by 161 is 2 with a remainder of 148.
Put 2 as the next digit of the answer. 
Result so far: 426637.45962732
Subtracting 322 from 470 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

The final result is 426637.45962732 with a remainder of 1.48e-07.
